Key Parameters

Substitute Part Grouping Explanation

Substitution of the CWR11MH105JD is determined by alignment of the following critical parameters:

Electrical Specifications: Capacitance value, voltage rating, and tolerance must match or exceed the requirements of the primary part.

Physical Form Factor: Package type, mounting configuration, and dimensional constraints must be compatible with the circuit board layout and assembly process.

Environmental & Compliance Ratings: Operating temperature range, MSL classification, and regulatory compliance status must satisfy application requirements.

Reliability Certifications: Automotive-grade qualifications (AEC-Q200) and failure rate specifications ensure performance consistency in demanding environments.

The substitute part TH3B105K035C4400 from Vishay Sprague is identified as a functional equivalent based on matching capacitance (1 µF), voltage rating (35 V), tolerance (±10%), and surface mount configuration.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The CWR11MH105JD remains the preferred choice when KYOCERA AVX supply is available and RoHS non-compliance is acceptable for the application. The part's Active status and unlimited MSL rating provide flexibility in storage and handling protocols.

Substitute Part Selection: The TH3B105K035C4400 from Vishay Sprague serves as a functional equivalent when supply of the primary part is constrained. This substitute maintains identical electrical specifications (1 µF, 35 V, ±10% tolerance) and physical form factor (1411/3528 Metric package, surface mount). The substitute carries AEC-Q200 automotive qualification, which may provide additional reliability assurance for applications requiring automotive-grade components.

Compliance Considerations: Both parts are RoHS non-compliant or unspecified in compliance status. Applications requiring RoHS compliance must evaluate alternative component families. The substitute part's AEC-Q200 certification indicates suitability for automotive applications with defined reliability requirements.

Inventory & Availability: The primary part maintains 1,038 pieces in stock. The substitute part has 20,448 pieces available, providing extended supply security when substitution is permitted by design specifications.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match between the primary part and substitute?

A: Capacitance value (1 µF), voltage rating (35 V), and tolerance (±10%) must be identical. These parameters define the functional performance of the capacitor in the circuit.

Q: Are the physical dimensions identical between CWR11MH105JD and TH3B105K035C4400?

A: Yes. Both components use the 1411 (3528 Metric) package with dimensions of 0.138" L x 0.110" W (3.50mm x 2.80mm) and maximum seated height of 0.083" (2.10mm). They are compatible with identical PCB footprints and assembly processes.

Q: What is the difference in ESR between these parts?

A: The TH3B105K035C4400 specifies an ESR of 4.4 Ohm. The CWR11MH105JD does not provide ESR specification in the available data. ESR affects high-frequency performance and ripple current handling; applications with strict ESR requirements should verify the primary part's specification with the manufacturer.

Q: Does the substitute part have automotive qualification?

A: Yes. The TH3B105K035C4400 carries AEC-Q200 qualification and is designated as automotive-grade. The primary part's automotive qualification status is not specified in the available data.

Q: Are there packaging format differences?

A: The primary part is supplied in Bulk packaging. The substitute is available in Cut Tape (CT), Digi-Reel®, and Tape & Reel (TR) formats. Packaging format selection depends on assembly process requirements and order quantity.

Q: What is the MSL rating of the substitute part?

A: The MSL rating for TH3B105K035C4400 is not specified in the available data. The primary part carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Confirm MSL requirements with the substitute manufacturer if moisture-sensitive handling protocols are required.

Q: Can these parts be used interchangeably in all applications?

A: Electrical and physical compatibility is confirmed. However, design specifications may impose additional requirements such as RoHS compliance, specific automotive certifications, or ESR limits. Verify all application-specific requirements before substitution.
